    Cellular Energetics is the broad term that encompasses both cellular respiration and photosynthesis and refers to how energy changes and reacts within cells. Cellular respiration is the process by which cells break down sugars (ATP) in order to produce energy for other chemical reactions. Cellular respiration takes place mainly in the mitochondria and the reactants in this process are oxygen and glucose and the main product in this process is ATP as well as waste products which include carbon dioxide and water. Almost all organisms perform cellular respiration. There are two types of cellular respiration…

    To be able to carry on metabolic processes in the cell, cells need energy. The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through cellular respiration. Cellular respiration is a catabolic pathway, which breaks down large molecules to smaller molecules, produces an energy rich molecule known as ATP (Adenosine Triphosphate) and a waste product that is released as CO2. Basically, cellular respiration is a metabolic process that releases energy from organic compounds (such as C6H12O6) by metabolic chemical oxidation in the mitochondria within each cell. Proteins, carbohydrates, and fats can all be broken down into fuel for the cell but cellular respiration is usually correlated with glucose. Cellular respiration also requires O2 to carry out its pathway, as oxygen will act as a final electron acceptor. So, the final equation that can be represented for Cellular Respiration is: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + heat.…

    Photosynthesis is the process by which plants create food for themselves which occurs in the cytoplast organ of the cell. They absorb carbon dioxide, water, and solar energy to produce glucose and oxygen (Doc C). Cellular respiration on the other hand, is the process occurring in the mitochondria by which organisms create energy to power cellular processes. This process takes in glucose and oxygen to create carbon dioxide, water, and energy in the form of ATP (Doc C). These processes follow the law of conservation of matter and energy as the amount of products is always equal to the amount of reactants in a chemical equation. So the amount of glucose and oxygen created during photosynthesis is equal to the amount of carbon dioxide and water used and the amount of carbon dioxide and water produced during cellular respiration is equal to the amount of glucose and oxygen used. Many people notice that the products of cellular respiration are the reactants of photosynthesis and the products of photosynthesis are the reactants of cellular respiration. This is because the two processes work together to provide organisms with food and…

    There are three total steps that Cellular Respiration goes through. The first step macromolecules into simple subunits, the second step is the breakdown of those newly made subunits. The second step changes those subunits into acetyl CoA, this is needed help make ATP and NADH. Step three is the final step, witch turn CoA into CO2 this is almost a short cut from electronic transport.…

    In cellular respiration and photosynthesis, the reactants flow through pathways to become products in very different ways. Respiration is catabolic, breaking glucose down, while photosynthesis is an anabolic reaction, building glucose. When respiration breaks glucose down, energy is released in small increments. The released energy is used to synthesize ATP, NADH, and FADH2. The NADH and FADH2 go through oxidative phosphorylation to produce ATP and H2O. Photosynthesis uses light reactions to provide energy to build glucose. Inside the thylakoids, where the light reactions take place, there are two types of photosystems, II and I. Photosystem II utilizes light…

    The respiration and photosynthesis cycle is the process by which plants and animals interact in a codependent and symbiotic manner to produce the nutrients, gases, and energy that they require to survive. Plants obtain energy from sunlight and use it to combine carbon dioxide and water into glucose and oxygen. This process is called photosynthesis. Animals eat plants containing glucose, and combine glucose and oxygen, releasing energy, water, and carbon dioxide. This process is called respiration. Plants take in carbon dioxide produced by animals, and release oxygen which animals require. Animals take in oxygen produced by plants, and release carbon dioxide which plants require. Plants obtain energy from the sun, store that energy in glucose, and animals obtain the energy stored in glucose by eating plants. Plant photosynthesis and animal respiration are symbiotic processes which occur in a continuous and cyclical manner, making life on Earth as we know it possible.…

    The process of mitosis and meiosis are both important to a living organism because without them a cell would not be able to reproduce. Mitosis is an asexual process used to replace old and dead cells with new ones by dividing into two identical daughter cells. Meiosis, however, is the step that makes sexual reproduction possible by taking a cell (diploid) and splitting it into two daughter cells (haploid) containing only half of the homologous pair.…
